RICHARD s. BRYANT, or CLnvELANn VEHICLE-WHEEL RIM'.

To all w/wm it may concern.'

Be it known that I, RICHARD S. BRYANT, a citizen of the United States,and ,a resident of Cleveland, county of Cuyahoga and State of Ohio, haveinvented anew and useful Improvement in Vehicle-lVhee'l Rims,

of which the following is a specification, the

which may then be' either permanently secured, or pressure-fitted, ontothe felly of the wheel, or may be demountably secured ontov such wheelfelly in order to permit of the more convenient interchange `andreplacement of the tires.

provemcnts relate more especially to rims for solid tires designed to bethus demount ably secured onto lthe wheel, although cer- 'tain featuresof construction embodied lvin such improvements may be also utilized inconnection with rims of this kind, irrespective of how they are mountedon the wheel.

The object of the invention is to provide a simple and inexpensive formof locking device for demountably securing such rims on the wheels, andparticularly solid tire rims of the kindin question, while still leavinga form and construction adapting them to be pressure-fitted to the wheelif desired.- At the same time the locking 'means are equally adaptablefor -use on single or dual tread Wheels. Av further object of theinvention is to provide a rim with its outer face so formed as to insurethat the tire base will firmly adhere thereto and not work loose,despite of vulcanization. To the accomplishment of the foregoing andrelated ends, the invention, then, consists of the means hereinafterfully described and particularly pointed out inthe claims.

The annexed drawings and the following description set forth in detail,certain'in'ech` anism embodying the invention, such disf` closed meansconstituting, however, but one of various mechanical forms in which theprinciple of the invention may be used.

In said annexed drawings:- Figure 1 is 'a transverse sectional view ofthe felly of a single tread wheel, showing a o'HIo, AssrGNon To COMPANY,oF CLEVELAND, oHIo, A CORPORATION oF oHIo.

solid-tire rim embodying my improved construction togetherfordemountably securing such rim in place; Fig. l*L illustrates, insimilar cross-section, the arrangement where such rim is pressurefittedonto the felly; Fig. 2 is a sectlon similar to that of Fig. 1, butillustrating the arrangement in the case of a dual tread rim, where tivorims are demountably secured on thewheel felly; Fig. 3 is a view ofadual tread wheel similar to that of Fig. 2, but showing a modificationin the construction of the rims and securing means therefor; and Figs. 4and 5 are likewise views similar to Fig. 2, but showing stillothermodifications in construction.

The tire-supporting rims 1 in the case of each provided withlaterlup-turnedflanges 2te incase the sides of the tire-base, and itwill be understood that the tread portion of the tire 3 may take on anydesired'form both in transverse and longitudinal cross-section, thetransverse section shown 'being merely typical; it will also beunderstood that the bases of such tires are vulcanized directly portionof the tire being usually less resilient than the bodyl and tread.

The outer face of the rim, to which the tire is thus vulcanized, may besimply plain, as illustrated in Figs 3 and 4, but preferablyand usually,such face is serrated, that is, p'rovided with a plurality ofcircumferentia better gri-p, or hold, for the tire.'- constructicn 'ofrim illustrated in Figs. 1 and 2, I illustrate sel-rations of this kind,such `serrations, however, being a particular creasing their utility.Thus it will beobserved that not merely is THE STANDARD WELDING with myimproved device grooves 4, (Figs. 1 and 2), thus increasing' the area ofcontact between the basel, of the tire and the rim, and also affordinga.

In the the base serra dis osed in manner, thereby materially 'inbut alsothe inner faces of the up-turned side flanges, the .serrations on theouter face proper, of the r1m, being of saw-tooth form formed whichadditionallya'ssists' in binding f pointing 1n opposite d'irec-"-the'lateral edges of the base firmly yto the those features of 'corie arlng nex g the rim to be secured on struction adapting the wheel body,orwheel 'proper'yn the formy illustrated in Figs 1 and 2, it will beobvserved that thelnner face of the is provided: with twocircumferential grooves 6 v adapted to receive corresponding tongues 7 t)"co1eratel with the wedge-rings, tachab .on Awedge-rings 8, which aretransversely split, and possess sufficient resihence to nor- Adaptedvmally be retained in such grooves.

.thus dey secured tothe tire-supporting rims,

are `two complementary wedge-rings 9, which seat directly on the outerface of thefellyjba'nd 10, that'surrounds the .felly 11 proper,

la) porting rim 1 and the. felly-band 10, such as usual. These twolast-named wedges are adapted to be forced 'inwardly by two clampingianges 12, that are secured against the respective faces of the felly bymeans of transverse bolts 13, having nuts 14:, adaptled` to draw suchflanges together. The lat.

ter may either be complete annuli, or ofscgmental construction, andproject radlally above the felly-band 10 a suiiicient distance to engagetheaforesaid wedge-rings 9 without -interferingV with thetire-supporting rim 1. i

awhere, as shown in 2, two I'ims re-` all four wedge-rings, thussimultaneously securing both rims on the wheel. v Where it is desired topressure-fit the rim onto the fe'lly, a plain annular band'16. (Fig.

and being of such thickness as to require considerable force to be thusinserted. f .fBy 'reason of the fact that the wedgerings 8 aredetachable from my improved tire supporting rims,- it will be obviousthat ythe latter may be readily prepared to be lthus pressure-fittedwithout requiring any 'special machining; Vin otherwords they arestrictly interchangeable for both methods of mounting, a featurey ofhigh importance, not merely in the hands of ,the user, who may desireftouse a spare rim on either of A they two types of wheel, but also' to themanu- 'inner single band-17 having its edges oppositely facturer,who isnot required to maintain a duplicate stock,

The construction illustrated in Fig. 3 differs from that shown in thefirst described figures only in that instead of a .pair of ,wedgefringsy8 detachably secured to the face of the tire-supporting rim, a

beveled, is thus secured by beingformed are. here equally wheel felly.,y

' integral shoulders is simply inserted between the tire-supwith atongue 18 adapted to fit into a corre- -spondingly disposed vgroove 19in the inner face of the rim.V The cooperating wedgerings 9,side-flanges 12 and intermedlate plain ring 15, where a dual arrangement1s desired, are exactly the same as 1n the previously describedconstruction. The rims well adapted to be pressurefitted instead ofdetachabfly, wedged-onto the The constructlon of rim `in Fig". 4, on thecontrary, is not thus adapted for interchangeable use, but still retainsthe feature of separable wedge-rings 20 on' the mner face of the tiresupporting rim for providing the co-acting beveled surface for thewedge-rings mounted on' the folly-band. These wedge-rings 20, however,do not have tongues adapted to lit into grooves on the face of the rims,but 4simply abut against 21 thereon. The arrangement of parts otherwiseis the same as Y in the preceding construction.

' In Flg. 5, the principal modification consists in the utilization of asingle centerring 22,insteadl of two wedge rings, such as rings 9, withan interposed plain ring 15. The' outer lateral edges 23 of said ringl22 are lbeveled to coperate with the inclined faces vof theA beveledribs on the inner face of the tire-supporting run, whether said vribs beof the kind shown in Figs. land 2, Fig. 3, or Fig. 4. The specific form'however,` of the ribs 24 illustrated in 5 corresponds most nearly withthat of the ribs 8 in said Figs. 1 and 2, differing therefrom only inthat the tongues 25 thereon slant at ari/angle to the body of the ring,so as to materially strengthen such rib, that is render it' less likelyto be broken off than when -it projects ata right angle. The grooves 26in the inner face of the correspond: in cross-section with the changedcross-section of such tongues.

roo

rim'. will, of course?` particularly those illustrated in Figs. 1, 2h

` and 3, iny addition to being interchangeable in the fashion abovedescribed, it should be noted, are capable of being fashioned out ofplain bands, that is, they do not require to be rolled special, so as tovprovide the integral wedge elements such as form the necessary featureof construction in .solid-tire rims at present onV the market. 'Ehenecessity for cutting away 'metal in order to face such wedges, is alsoeliminated. The pairedwedge-rings used at both sides, may obviously bemade identicalso as to be interchangeable and adaptable forv use withall' profiles. It will accordingly be seen that both in construction anduse, a marked simplification is found in the present rim.'l
